TL;DR - What are you running as a means of “antivirus” on Linux servers?
I have a few small Debian 12 servers running my services and would like to enhance my security posture. Some services are exposed to the internet and I’ve done quite a few things to protect the services and the hosts. When it comes to “antivirus”, I was looking at ClamAV as it seemed to be the most recommended. However, when I read the documentation, it stated that the recommended RAM was at least 2-4 gigs. Some of my servers have more power than other but some do not meet this requirement. The lower powered hosts are rpi3s and some Lenovo tinys.
When I searched for alternatives, I came across rkhunter and chrootkit, but they seem to no longer be maintained as their latest release was several years ago.
If possible, I’d like to run the same software across all my servers for simplicity and uniformity.
If you have a similar setup, what are you running? Any other recommendations?
P.S. if you are of the mindset that Linux doesn’t need this kind of protection then fine, that’s your belief, not mine. So please just skip this post.
Running a honey pot for SSH and sharing logs only proves that people try to attack you, it does not really tell if SSH as such is vulnerable or not. It is a honey pot, people gaining access if the whole point.
Having a locked down but exposed SSH access is something else.
You’re missing my point, a virus doesn’t have to infiltrate a completely secure system. It can come through you accidentally leaving your ssh insecure or any other service.
I get that a malware can get inside the worlds most secure system, if for example a user lets it in. What I am saying is that showing a honey pot in response to “ssh is more secure than a software that runs code without you giving consent and without your knowledge” not say anything, except what happens if someone gets in.
